life and work

Druțu attended what is now the National College Emil Racoviță in Iași. She earned a Bachelor and Master degree in mathematics from the Technical University "Gheorghe Asachi" Iași . In 1996 she did her doctorate in mathematics at the University of Paris-Süd in Orsay with Pierre Pansu with the dissertation Réseaux non uniformes des groupes de Lie semi-simple de rang> 1: invariants de quasiisométrie . In 2004 she habilitated at the Lille University of Science and Technology . In 2009 she became Professor of Mathematics at the Mathematical Institute at the University of Oxford. She was a visiting researcher at the Max Planck Institute for Mathematics in Bonn , the IHES in Bures-sur-Yvette and the MSRI in Berkeley , California , and did research as part of a Simons Fellowship at the Isaac Newton Institute in Cambridge . She currently chairs the joint scientific committee of the European Mathematical Society and the European Women in Mathematics .

She deals with geometric group theory . With Mark Sapir , she characterized relatively hyperbolic groups by a “tree-graduated” structure of their asymptotic cones .
